HKS GT2540

[Foxcolt]

Please anyone who's had Experience With this turbo only.

How much power can I expect?
When does spool start?
When does full boost come on?
Since it's internal wastgate what is stock boost at?
How much PSI can I run with it max?
What are the differences between gt2540 & gt2530?
Can you rebuild it?
Are the oil and water lines same as stock t25?
How much should I expect to pay for it?

Also on the topic of fuel it looks like I have three options please give your opinions.

1, JWT Ecu pro: plug and play con: seems like the turnaround time is 5 weeks since there are backed up.

2, Super AFC Pro: Cheap Con: have no clue how to tune it since I've had no experience with it. Doesn't seem to be very accurate either.

3, Power FC Pro: Oh so cool!! Con: Once again would have no idea how to tune it and doubt any shops in my area have any experience either.

Please tell me what you think.

Thanks a million
